这是一个C语言与汇编混编的例子实现绘图，调试环境为TC2.0或者TC3.0。运行这个程序需要tc提供的几个头文件。建议修改options菜单中的include目录项到tc的include的目录下(具体方法可以参见本书第一章的讲解)；或者把源程序拷贝到tc目录下运行。

而本章例子中，因为MICROCAD.C内嵌汇编代码，读者要在命令行下输入tcc -B D:\TC\source\MICROCAD\MICROCAD.C，来编译MICROCAD.C。注意，在汇编的时候TC要调用TASM.exe。-This is a mixed compilation of C language and examples of the realization of graphics, debugging environment TC2.0 or TC3.0. Tc need to run this procedure provides several header files. Proposed to amend the options menu items include directory to the include directory tc (for specific ways to see the first chapter of this book to explain)　or copy the source code to run tc directory. The examples in this chapter because MICROCAD.C inline assembly code, the reader to the command line, enter the tcc-BD: \ TC \ source \ MICROCAD \ MICROCAD.C, to compile MICROCAD.C. Note that when in the compilation of TC to call TASM.exe.
